coveringof such a nature as to cover and' protect the luminous matter without destroy- .ing the luminosity, and at the same time to withstand the impact of the club w thout fracturing.

A construction designed to carry out the invention will be hereinafter described to- I gether with other features of. the invent on.

The invention will be more readily understood from areading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:

in accordance with my 1nvention, a portion of the covering being omitted,

Fig. 2 1s a diametrical cross-sectlonal view taken on the line 22 of Fig. 1,

I 'Fig. 3 is a view similar to Fig." l of another form of the invention, and

Fig. 4 is a diametrical cross-sectional view.

.taken on the line 44' of Fig. 3.

In the drawings, the numeral IO'desig- 'nates a golf ball of any suitable construction, the surface of which is formed with spaced sumps or recesses 11, WhlCll may be concaved or otherwise sha ed in cross-section. These sumps may be regularly spaced apart or rouped, or arranged in desirable-manner. VV-hile I have shown and described a golf ball, the invention may be applied to any analogous. ball. A suitable luminous composition or material 12, such" as radium pamt many other material 1 whereby said around theball.

,of a celluloid or coating 12 any other having radium'or equivalent material as its base is filled into the sumps flush with the surface of the body of the ball, thus forming the ball.

luminous buttons or spots on the surface of In order to protect these buttons "a trans parent jacket or covering 13 is molded This jacket may be formed pyroxylin compositiomor any of the well known transparent coating; now in common use The coating must be tough enough to withstand the impact of the club Without fracturing orchipping off and must also snugly embrace or adhere to the ball. I

It is evident the invention maybe applied to the ball in various Ways. For instance in Figs. 3and 4 I have shownthe ball 10 having a smooth surface, but this is. not essential, and entirelycoated with a luminous and covered with the jacket 13.

Numerous other forms have not bee illusv trated. Fig. 1 is a View of a golf ball constructed A'ball made in accordance with my invcn-' tion may be readily located at night or in dark places owing to its luminosity. Such a ball will enable the'playing of golf and similar games at night and permit the finishstopped becauseof darknessQ Various changes in the size, shape and design of the ball as well as modifications and,

alterations may be made within the scope of the appended claim. 1

hat I claim is:
